The Best Performing LEGO Theme from 2025 for Investing (It's Not What You Think)
I told people these sets would perform, I hope everyone listened!
This post is brought to you by me.
If you’re going to invest in LEGO, you need to keep track of your investments.

When most people think about LEGO investing, they gravitate toward obvious themes like Star Wars, Harry Potter, Minecraft.
The Ideas theme rarely comes up in that conversation.
That’s exactly why it keeps printing.
Here’s a look at every 2025 retiree from the Ideas theme and how they’ve performed:
Theme Average ROI: 50.2%
For context, the average ROI across all 2025 LEGO retirees after almost three months is roughly 20%.
Ideas is more than double that.
Six of these seven sets were on the TIE 2025 Hit List.
The only “underperformer” in the bunch is the Motorised Lighthouse at 6.7%, which is due to Amazon stocking them until just a couple weeks ago.
Trust me, almost no one bought that set so it will hit $500+ in the coming weeks/months.
Did you know you could have bought it at the exact same time as me back in January?
I sent a buy alert for it right here inside this newsletter, which you can read here:
The Sanderson Sisters Cottage is already north of 50% ROI.
Imagine what that is going to do come Halloween…
This is what a clean sweep looks like.
Why Ideas specifically?
The sets appeal to adults with disposable income, not children.
They look intricate and are incredibly detailed.
If you were going to pick one theme that has the best looking sets to sit on a shelf after you’ve built them, Ideas is your theme.
If you’ve been on the fence about sealed LEGO investing, this is what the data looks like when you pick the right theme.
It just so happens that three Ideas sets are retiring this July.
That means the best time to buy those sets is between now and then.
If you want to see which three sets I’m talking about, I recommend you read the latest edition of the TIE 2026 July Hit List post I put out last week:
The cool part about sets that retire in July is that you have an opportunity to sell them for a profit less than six months later.
You don’t have to (I usually hold for ~18 months before selling) but having that option is extremely valuable.
Then again, you could just ignore all of this and not take advantage of it at all because you hate money.
The choice is yours.
